Electrocardiograph

Abstract

The invention discloses an electrocardiograph. The electrocardiograph comprises a main shell, a main unit arranged in the main shell, six chest leads and four limb leads, wherein the six chest leads and the four limb leads are electrically connected with the main unit; the electrocardiograph is characterized in that chest lead wires comprise chest lead wire cores and chest lead wire wrappers, thechest lead wire wrappers are internally provided with chest lead metal mesh layers, and limb lead wires comprise limb lead wire cores and limb lead wire wrappers; the limb lead wire wrappers are internally provided with limb lead metal mesh layers, and the chest lead metal mesh layers and the limb lead metal mesh layers are electrically connected with the ground terminal of the main unit. Throughthe line arrangement type leads and arranged obviously-unequal-length free ends in accord with the human body parts, installing positions of different leads are clearly reminded to avoid confusion, the lead wire strength is enhanced through the metal mesh layers arranged in the lead wire wrappers, and twisting is resisted; lead wire twining is avoided, the lead wires are quickly collected throughan automatic wire collection device, it is ensured that after using, the lead wires cannot be disordered, and the problem of lead wire twisting and twining is solved fundamentally.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electrocardiograph. Background technique [0002] The electrocardiogram function can automatically record the bioelectrical signal generated by the myocardial excitement when the heart is active, that is, the electrocardiographic signal. It is a medical electronic instrument commonly used in clinical diagnosis and scientific research. The electrocardiogram machine is a necessary inspection equipment for hospitals and outpatient clinics. It is used to detect the ECG waveform of the human body to diagnose heart-related diseases. The diagnosis of heart disease has irreplaceable value. The electrocardiograph includes a main unit and multiple leads. The leads include six chest leads and four limb leads. The chest leads and limb leads transmit the picked-up human ECG signals to the main unit. After the main unit amplifies and filters the signals, the different lead The relative po...

Problems solved by technology

[0003] The current electrocardiograph has several problems that have not been perfectly solved. The first problem is interference

The potential of the ECG signal is very low, and the connecting wires of each lead are relatively long, which is easy to receive various electric induction signals. The electric fields of various electrical appliances in the general room will also be received by the long leads, which will interfere with the human heart. The electrical signal, the surrounding electric field and the ECG signal are confused, which makes the output waveform of the ECG disordered and it is difficult to correctly reflect the condition

In response to this situation, the main method currently adopted is that the patient’s body should not touch any metal objects during the electrocardiogram, and try not to let other people touch it. Avoid preventing high-power electrical appliances in the room. The above measures can reduce the interference signal of the human body, but in general is very passive

[0004] The second problem is that the connecting wires of the leads are easily entangled. At present, the connecting wires of all the leads on the ECG machine are independent, because different leads detect different positions of the human body, and it is difficult to use a single wire to set them up uniformly.

And multiple connecting wires will cause the connecting wires to be easily entangled with each other and not easy to separate. The doctor must straighten out the connecting wires every time he performs an ECG examination for the patient. According to the label and color on the plug of each wire Determine which part of the wire is connected, which undoubtedly reduces the inspection speed, prolongs the inspection time, and is more likely to delay rescue during emergency
